小麦株型分类探讨
Classification of wheat plant types
【摘要】 对小麦的狭义株型从不同角度进行定性分类,提出了量化指标。根据茎秆分布形态,小麦的株型可分为W型、V型、桶型、长条型、线状型等基本类型。一般常把小麦株型分为扩张型、松散型和紧凑型三类。通过试验比较植株茎秆的收敛程度认为:用形态特点描述株型更为准确合理,且易于量化描述和品种辨别。
【Abstract】 The plant types of wheat in narrow sense were quantitatively classified,and some quantitative indices were brought forward.Based on the distribution pattern of stems,the wheat plant types were classified into W,V,barrel,strip and linear types,and so on.However,it was usually classified into outspread,incompact and tight types according to the convergent exponents of clum.And after the experiments,it was considered that plant morphological characteristics were more accurate and reasonable to quantify and to classify the plant types.
